Installing Audacity
Audacity is not installed by default in Ubuntu. To start using Audacity, install the package audacity from the Universe software channel. For more information on installing packages, see InstallingSoftware.
Once installed, click Applications -> Sound & Video -> Audacity to start Audacity.
Troubleshooting
After installation, you may receive the error message "Error Initializing Audio" with the explanation "There was an error initializing the audio i/o layer. You will not be able to play or record audio. Error: Host error."
To start Audacity without this error, press the Alt + F2 keys on your keyboard and type the following into the box which appears:
gksudo audacity
If Audacity now starts without the error message, you can alter its menu entry with the new command by using the Alacarte Menu Editor. To start Alacarte, select Applications -> Accessories -> Alacarte Menu Editor. Note that you will need to install Alarte first. See InstallingSoftware.
If this method does not work, you can alternatively press the Alt + F2 keys on your keyboard and type:
aoss audacity
This will run Audacity through the ALSA sound wrapper, instead of Audacity's default, OSS. For more information, see alsa-oss.
Intrepid
The version of Audacity provided in the standard Ubuntu repositories does not work with PulseAudio, the default audio server. David Henningsson has built fixed packages; they can be installed by adding his PPA as described in https://edge.launchpad.net/~diwic/+archive. In Intrepid, I noticed that I could not play audacity files while other sound programs were open. For example, rhythmbox or firefox after visiting youtube. When I tried to play a file the error that Audacity printed was
Error while opening sound device. Please check the output device settings and the project sample rate.
When I went to preferences no output devices were listed in the drop down menu. I worked around this by quitting all other sound programs and then Audacity would play sound. I think this issue has already been reported and the patch is included in Jaunty. https://bugs.launchpad.net/ubuntu/+source/audacity/+bug/178895/comments/40
Locating libmp3lame.so When Exporting MP3 Files
By default, the library libmp3lame.so is not installed in Ubuntu. To install this library, install the package liblame-dev from the Multiverse software channel. (For more information on installing packages, see InstallingSoftware.)
When Audacity asks you to locate libmp3lame.so, you will be able to locate it in /usr/lib and export MP3 files.
